7 terms
Activated Complex
Chemical Kinetics & Catalysis
kJ/mol
The transient arrangement of atoms present at the transition state, poised between reactants and products.
Activation Energy
Chemical Kinetics & Catalysis
kJ/mol
The minimum energy that colliding particles must possess for a reaction to occur.
Ea = E(transition state) − E(reactants)
Active Site
Chemical Kinetics & Catalysis
Dimensionless
The specific region of a catalyst or enzyme at which the reacting molecules bind and are transformed.
Adsorption
Chemical Kinetics & Catalysis
mol/g
The accumulation of molecules of a gas or liquid on the surface of a solid.
Arrhenius Equation
Chemical Kinetics & Catalysis
Various
The equation describing how a rate constant varies with temperature and activation energy.
k = A e^(−Ea/RT)
Autocatalysis
Chemical Kinetics & Catalysis
Dimensionless
Catalysis of a reaction by one of its own products.
Average Rate
Chemical Kinetics & Catalysis
mol/(L·s)
The overall change in concentration divided by the total time interval over which it occurred.
rate_avg = Δ[A] / Δt
